Why do cells need to regulate what goes in and out of them?

Biology
1 answer:
kap26 [50]2 years ago
5 0

Answer: These molecules are essential for living things. The cell membrane controls what goes in and out by having protein channels that act like funnels in some cases and pumps in other cases. Passive transport does not require energy molecules and happens when a funnel opens in the membrane, letting molecules flow through.

Explanation: Hope this helps :)

Intercostal nerves Group of answer choices are also known as cervical nerves. do not enter into a plexus and directly connect to
Natali [406]

Answer:

The correct answer is: do not enter into a plexus and directly connect to the structures they supply.

Explanation:

<u>The </u><u>anterior rami</u><u> of the thoracic spinal nerves </u><u>from T1 to T11</u><u> give birth to the </u><u>intercostal nerves</u>, which are part of the somatic nervous system.

The intercostal nerves supply the thoracic pleura and abdominal peritoneum, and they vary from the anterior rami of the other spinal nerves in that they each take their own path without forming a plexus, <em>directly connecting to the structures they supply</em>.

The intercostal nerves are derived from the somatic nervous system, unlike the autonomic nervous system nerves that innervate the visceral pleura of the thoracic cavity. They can govern muscle contractions and give sensory information about the skin and parietal pleura as a result of this. This explains why damage to the thoracic cavity's interior wall can be felt as a severe discomfort in the damaged area. Damage to the visceral pleura causes a pain that is not localized.

What has allowed animals to adapt over time?
jeka94

Natural selection ensures that animals with features that increase their chances of survival are more likely to live and pass those traits on to their progeny.

Animals adapt to their surroundings over a lengthy period of time, which causes those changes. The evolution of adaptations happens across many generations.

<h3>What is an adaptation?</h3>
  • A physical or behavioral characteristic of an animal that enhances its ability to survive in its environment is known as an adaptation.
  • To put it another way, an adaptation is something a species does or has on them that makes it easier for them to locate food, water, mates, and shelter.
  • Among the adaptations that helped animals live and prosper on land are:
  1. Gas exchange using a moist membrane
  2. The ability to traverse land (limbs instead of fins)
  3. The capability of body water conservation
  4. The capability of reproduction and early habitability
  5. The capacity to endure fast environmental changes
<h3>What are the types of adaptation?</h3>

Depending on the environment, there are three basic types of adaptations: behavioral, structural, and physiological.

  • Physiological- When an animal's body's internal mechanisms adapt to its surroundings.
  • Structural - Over the course of millions of years of evolution, the animal's bodily features alter.
  • Behavioral - Animals adjust their behavior in reaction to their environment.
